Know what takes waterproof eye makeup off more easily than you'd expect? Clean & Clear Makeup Dissolving Facial Cleansing Wipes ($7.49 for 25 sheets), that's what. And without stinging your eyes. I used them to take off the CARGO waterproof pencil. Completely.
Colour me surprised. And my wallet happy.
